While general field upgrades of 59x systems at firmware release level SF230 (or earlier) to firmware release level SF235 are not being performed, this release level was shipped on 59x systems shipping from manufacturing between October 2005 and May 2006.

Concurrent update to the latest service pack within the SF235 Release is available to customers via ECA 828.

Model 590 and 595 Recommendations:

Systems Currently at Release Level SF230:
Customers not requiring the function being provided in later firmware releases can stay at their current level and continue to receive fixes via Service Packs to minimize disruption to their operations. Product Engineering recommends the concurrent installation of ECA 827 (minimum level SF230_156) during your next firmware maintenance window.

Customers with model 59x servers at firmware level SF230_xxx  who would like to enable the Redundant FSP/Node failover capabilities or upgrade their firmware to a new release boundary (i.e. SF240_xxx)  for any reason should call 1-800-IBM-SERV and request ECA815.  IBM will dispatch a Service Representative to complete this upgrade for you.

Systems Currently at Release Level SF235:
Product Engineering recommends the concurrent installation of ECA 828 (minimum level SF235_206) during your next firmware maintenance window.

NOTE:  Note: For 9119 systems with release level SF235 installed, an ECA is not required to upgrade to release level SF240.
